      abstract     = {The origin of the complex reflection splitting in potassium
                      sodium niobate doped with lithium and manganese was
                      investigated using temperature-dependent high-resolution
                      X-ray and neutron diffraction as well as electron probe
                      microanalysis and scanning electron microscopy. Two
                      structural models were developed from the diffraction data.
                      A single-phase monoclinic Pm model is known from the
                      literature and is able to reproduce the diffraction patterns
                      perfectly. However, a model with phase coexistence of two
                      classical orthorhombic Amm2 phases can also reproduce the
                      diffraction data with equal accuracy. Scanning electron
                      microscopy in combination with electron probe microanalysis
                      revealed segregation of the A-site substituents potassium
                      and sodium. This favours the model with phase coexistence
                      and confirms the need for comprehensive analyses with
                      complementary methods to cover a broad range of length
                      scales as well as to assess both average and local
                      structure.},
